Is this a bug?---sometimes I can't get rid of a particular search result window-no matter how many times I click on the "X". And although I have set prefs to allow 10 searches at once, after I have, say 5 search result windows, as I say-I can't get any of them to disappear, and new searches I try to initiate don't show up after I punch "search" on the left. Bugger it! What am I doing wrong? Or is it not me?? Help!

Since you posted this in OS X supprt, I'm going to make a leap and say you have OS X. If so, download Jum's build of Limewire for OS X at http://baghira.han.de/~jum/. It fixes numerous minor bugs exactly like the one you described.
